And I would like to create a concatenated Altair chart like the one below:

Concatenated Altair chart example

I have this so far but this is not working :

alt.Chart(prob_df).alt.Chart(prob_df).mark_line().encode(
    x='Key2',
    y='Year'
).properties(
width=150,
height=150
).facet(
facet='Key1',
columns=3
)

What would be the best way to create a graph for this

Solution

  • This should work:

    alt.Chart(prob_df).mark_line().encode(
    x='Year',
    y='Prob'
).properties(
    width=150,
    height=150
).facet(
    row='Key1',
    column='Key2'
)
